VC++ 跟随父窗口调整控件大小

3、在WM_SIZE的响应函数OnSize()中加入以下代码：

1：private:
CRect m_rect;

2：GetClientRect(&m_rect);

3：

void CButtonDlg::modify(CWnd* pWnd,int cx,int cy)
{
if (pWnd)
{
CRect rect; //获取控件变化前大小
pWnd->GetWindowRect(&rect);
ScreenToClient(&rect); //将控件大小转换为在对话框中得区域坐标

//cx/m_rect.Width()为对话框在横向的变化比例
rect.left = rect.left * cx/m_rect.Width();
rect.right = rect.right * cx/m_rect.Width();
rect.top = rect.top * cy/m_rect.Height();
rect.bottom = rect.bottom * cy/m_rect.Height();
pWnd->MoveWindow(rect);
}
}

void CButtonDlg::OnSize(UINT nType, int cx, int cy) 
{
CDialog::OnSize(nType, cx, cy);

CWnd* pWnd1 = GetDlgItem(IDC_BUTTON1);
CWnd* pWnd2 = GetDlgItem(IDC_BUTTON2);
CWnd* pWnd3 = GetDlgItem(IDC_BUTTON3);
CWnd* pWnd4 = GetDlgItem(IDC_BUTTON4);
CWnd* pWnd5 = GetDlgItem(IDC_BUTTON5);

modify(pWnd1,cx,cy);
modify(pWnd2,cx,cy);
modify(pWnd3,cx,cy);
modify(pWnd4,cx,cy);
modify(pWnd5,cx,cy);

GetClientRect(&m_rect);//获取新的对话框的大小
}
